apple-watch - 使用 IOS 数据更新 WatchOS2 ClockKit 并发症

Question

我正在尝试使用通过 WatchConnectivity 从 IOS/iPhone 传输的数据更新 watchOS2 时钟套件并发症。

尽管进行了相当多的研究，但迄今为止未成功。我发现虽然其他帖子描述了类似的挑战(还没有解决方案)

我面临3个问题:

1) 来自 ComplicationController 的 sendMessage 似乎没有唤醒 IOS 父应用程序(而从 InterfaceController 发送的相同 sendMessage 确实唤醒了 IOS 父应用程序)

2)即使将值传输到 ComplicationController(通过 sendUserInfoToComplication 并且当 IOS 应用程序处于前台时)，显示在复杂功能中的值也只是有时会更新(还没有找到模式为什么有时会/有时不会)

3) 我将“getNextRequestUpdate..”设置为 2 分钟(用于测试目的)。不过，这似乎没有任何区别。 (即使在任意时间在模拟器中也被触发，但未使用“预算”/我设置了塞子来验证)

请注意，我对 IOS/Swift 编程比较陌生。但是我看到，根据其他问题/帖子，我似乎并不是唯一一个为此苦苦挣扎的人。

这里的示例代码:

此外，在运行模拟器时，我会收到大量与以下内容类似的消息:

objc[7501]: Class SPAssetCacheAssets is implemented in both /Applications/Xcode.app/Contents/Developer/Platforms/WatchSimulator.platform/Developer/SDKs/WatchSimulator.sdk/System/Library/Frameworks/WatchKit.framework/WatchKit and /Applications/Xcode.app/Contents/Developer/Platforms/WatchSimulator.platform/Developer/SDKs/WatchSimulator.sdk/System/Library/PrivateFrameworks/SockPuppetGizmo.framework/SockPuppetGizmo. One of the two will be used. Which one is undefined.

Answer 1

使用 CLKComplicationServer像这样:

CLKComplicationServer* server = [CLKComplicationServer sharedInstance];
[server.activeComplications enumerateObjectsUsingBlock:^(CLKComplication * _Nonnull each, NSUInteger idx, BOOL * _Nonnull stop) {
    [server reloadTimelineForComplication: each];
}];

它将调用您的 ComplicationController .
